trans-Diaquabis[5-(1H-imidazol-4-yl-N³)-1H-tetrazolato-N¹]zinc(II)

H. Zhao and J. Xiao

Abstract: In the title complex, [Zn(C₄H₃N₆)₂(H₂O)₂], the metal centre lies on an inversion centre and displays a distorted octahedral ZnN₄O₂ coordination geometry. The organic ligand is not planar; the dihedral angle between the imidazole and tetrazole rings is 8.39 (9)°. An extended network of intermolecular N-HN and O-HN hydrogen bonds stabilizes the crystal structure.
